Microtubules are involved in a wide variety of cellular activities ranging from mitosis and transport events to cell movement and the maintenance of cell shape. Tubulin itself is a globular protein which consists of two polypeptides (alpha and beta tubulin). Alpha and beta tubulin dimers are assembled to 13 protofilaments that form a microtubule of 22 nm diameter. Tyrosine ligase adds a C-terminal tyrosin to monomeric alpha tubulin. Assembled microtubules can again be detyrosinated by a cytoskeleton associated carboxypeptidase. Detyrosinated alpha tubulin is referred to as Glu-tubulin. Another post-translational modification of detyrosinated alpha tubulin is C-terminal polyglutamylation which is characteristic for microtubules in neuronal cells and the mitotic spindle.
Alpha tubulin is not suitable as a loading control in adipose tissue as expression of tubulin in adipose tissue is very low ( Spiegelman and Farmer, Cell, 1982, 29(1): 53-60, "in cells undergoing adipose differentiation actin synthesis decreases by 90%").

This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using Licor blocking buffer before being incubated with ab89984 overnight at 4°C. Antibody binding was detected using ab175787 at a 1:10,000 dilution for 1hr at room temperature and then imaged using the Licor Odyssey CLx.

ab89984 staining alpha Tubulin in SV40LT-SMC cells. The cells were fixed with 4% formaldehyde (10 min), permeabilized in 0.1% Triton X-100 for 5 minutes and then blocked in 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab89984 at a working concentration of 1μg/ml and ab195889, Mouse monoclonal [DM1A] to alpha Tubulin (Alexa Fluor® 594, shown in red) at 1/250 overnight at +4°C, followed by a further incubation at room temperature for 1h with an anti-chicken AlexaFluor® 488 (ab150173) at 2 μg/ml (shown in green). Nuclear DNA was labelled in blue with DAPI.This product also gave a positive signal in 100% methanol (5 min) fixed SV40 cells under the same testing conditions.Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

The cells were then incubated with ab89984 at 5μg/ml and ab7291 at 1µg/ml overnight at +4°C, followed by a further incubation at room temperature for 1h with an AlexaFluor®488 Goat anti-Chicken secondary (ab150173) at 2 μg/ml (shown in green) and AlexaFluor®594 Goat anti-Mouse secondary (ab150120) at 2 μg/ml (shown in pseudo color red). Nuclear DNA was labelled in blue with DAPI.

The cells were fixed with 100% methanol (5min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1%PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab89984 at 5μg/ml (shown in green). Nuclear DNA was labelled with DAPI (shown in blue).Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

ICC/IF image of ab89984 stained HeLa cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal Goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab89984 at 5ug overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 Goat anti- chicken IgY (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in HepG2 PFA fixed cell types at 5ug/ml.
